Officials at the National Information Assurance Partnership have effectively raised the level of security in many information technology products used by the government, the security group's director said today.

The aim of NIAP, an initiative of the National Institute of Standards and Technology and the National Security Agency, is to increase the level of trust users have in their information systems through the use of security testing, evaluation and validation programs. To that end, NIAP officials are responsible for implementing the Common Criteria Evaluation and Validation Scheme, a rigorous set of security tests that adhere to international standards. NIAP officials provide technical guidelines to eight commercial laboratories which conduct the tests.

Statistics gleaned from the labs' Common Criteria work indicates that the testing is improving security, said Jean Schaffer, director of NIAP. Schaffer spoke during a session at a Federal Information Assurance Conference held this week at the University of Maryland.

So far, 100 percent of the products evaluated have been approved, she said. The testing directly improved 30 percent of the products tested by eliminating security flaws that could have been exploited by attackers. About 40 percent of the products evaluated were improved by the addition or extension of security features, Schaffer said.

Critics say Common Criteria testing costs too much and takes too long, but Schaffer argued that these claims are made by those who do not have firsthand knowledge about the testing. Feedback from the labs shows that testing for Evaluation Assurance Level (EAL) 2 — the minimum level of security, which includes products such as firewalls, intrusion-detection systems, routers and switches
